title: 2-(4-Bromo-phen-yl)-N-(pyrazin-2-yl)acetamide.
abstract: In the title compound, C12H10BrN3O, the dihedral angle between the mean planes of the 4-bromo-phenyl and pyrazin-2-yl rings is 54.6 (3)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) graph-set motif. In the crystal, weak N-H⋯N hydrogen bonds link the mol-ecules into chains along [100]. The chains are linked via C-H⋯N and C-H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to the ab plane.
